Gold and Silver Leaching by Cyanidation

Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.

The method of extraction of precious metals

Leaching of gold is first made with oxygenated water and then with gold-free oxygenated circulating solutions without addition of cyanide. Circulating solutions have pH= 8-10, C NaCN =0.1-0.2 g/l. Proposed method ensures high daily concentration of gold in production solutions of about 4-22 mg/l including increase of extraction of gold by 80-85%.

Gold and Silver Leaching by Cyanidation

Elsner's equation is generally accepted as expressing the action of gold in dilute cyanide solutions; 4 Au + 8 KCN + O2 + 2 H2O = 4 KAu (CN)2+ 4 KOH. Thus, when fresh surfaces of gold are exposed to the action of cyanide in an aqueous solution containing free oxygen, a gold cyanide compound will be formed and a hydroxide (alkaline).
